    Get both ends of the elastic band and pull them down either side of the pen, and sticky tape the ends of the elastic band onto either side of the pen with a little bit of the ends still out so you can turn them back over the sticky tape, and fold the ends over and tape them down again, to acquire greater holding and a lower chance of hurting one's self.

  • Question
    Will a high powered pen gun hurt someone?
    Community Answer
    Community Answer
    If fired at close enough range, then yes. The pen has a sharp point that can prick skin.

    Can it hurt people?

    If shot at close range, it might. Remember to be careful with projectiles and to never shoot at the facial area or other sensitive spots.
  • Question
    What can I use other than the ink cartridge for ammo? I want to have options where I can carry more than one piece of ammo at a time.
    Community Answer
    Community Answer
    Capri Sun straws, possibly. Perhaps toothpicks or sticks.
